Answer:
Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.
The radius is 15 feet.
Multiply.
Now we know the diameter. Substitute 30 feet in for d.
We are using 3.14 for pi, so substitute it in.
Multiply.
The circumference of the circle is 94.2 feet.

Answer:
This is incomplete, but i will answer it in a general way.
A function is something like y = f(x)
You can think in a function like a "machine", that eats an input (x) and transforms it into an output (y).
The functions have a rule: For all the possible inputs, the function can transform them into only one output.
This means that if we have for an input x1.
f(x1) = y1 and f(x1) = y2
So f(x) maps x1 into two different values, y1 and y2, then this is not a function.
Now, you want to change the point (1, 4) of a relationship in order to transform it into a function (so in the relation R we have two points with x = 1, and differet values of y). Then you need to choose the option that in the x-component does not have the same value that one of the other data points of the relation.
